Part of being human is to experience moments of true perception about those things that touch you so intimately that suddenly you see. What you see (or read or hear) at such moments has a ring of truth about it, not just of a general kind but as something that takes on a dimension and depth for you so that it becomes your truth. It seems to be making a claim on you. Such moments don't come often. Hold on to them. Cherish them until they become so much a part of you as to be second nature. For there is only one persistent demand made upon us by the Spirit. It is that we are receptive. That we keep our eyes open, our minds unclosed. It is, in short, that we retain all our lives our sense of wonder.
Dom Henri le Saux, a French Benedictine monk, suggests that the sacred sound "OM" can be used by anyone:
More than any particular name of Divinity, OM conveys the ineffability and the depths of the divine Mystery. It bears no distinct meaning ... It does not even recall any mythological or semi-historic event. It is a kind of inarticulate exclamation uttered when you are confronted with the Presence in yourself and around yourself.
You could say that OM is a name of God which is not a name.
